SAFETY CODE FOR WOODWORKING PLANTS
INTRODUCTION
1. This woodworking safety code is primarily intended to cover
the hazards o f the “ point o f operation ” in woodworking machinery
from the crude lumber to the finished product.
2. This code is one o f a series intended ultimately to cover all
American industry which are being prepared under the procedure o f
the American Standards Association.
3. The code is in form to be adopted by States and municipalities
or promulgated by order o f an industrial commission.
4. It may also be used by industrial establishments which use
woodworking machinery to test and standardize their safety equip­
ment.
5. The code will be revised from time to time to keep it abreast
with the advances o f safety practice.
SECTION 1. SCOPE, APPLICATION, AND EXCEPTION

Rule 10. Scope.
This code is intended as a guide for the safe operation and main­
tenance o f woodworking machinery, including cooperage and making
o f veneer. It deals primarily with “ point o f operation ” hazards on
woodworking machinery.
Rule 11. Application and exceptions.
The purpose o f this code is to provide reasonable safety for life,
limb, and health. In cases o f practical difficulty or unnecessary
hardship the enforcing authority may grant exceptions from the
literal requirements o f this code or permit the use o f other devices
or methods, but only when it is clearly evident that equivalent pro­
tection is thereby afforded.
N ote .— It is suggested that when exceptions are asked the enforcing authority
consult with the Committee on Safety Code for Woodworking Plants, care
American Standards Association, 29 W est Thirty-ninth Street, New York City.
Such consultation will tend to bring about uniform application of the code and
will keep the committee informed of criticisms which should be considered.

Rule 12. New and old installations.
A fter the date when this code becomes effective all new construc­
tion and installations shall conform to its provisions. Equipment
installed prior to that date shall be modified to conform to its pro­
visions unless exception is allowed in accordance with rule 11.

Rule 112. Aisles.
Aisles o f sufficient width to permit the passing o f trucks and
workmen without crowding shall be maintained in all working
places and stock rooms.
PART II.— MACHINES AND EQUIPMENT
SECTION 20. MACHINE DRIVE, FEED, SPEED, AND CONTROL

Rule 200. Machine drive.
(a)
It is recommended that careful consideration be given to the
advantages o f individual motor drive.
( i ) Not more than 10 machines should be driven by a single
motor or other power unit.
(c) A mechanical or electrical power control should be provided
on each machine which will make it possible for the operator to cut
off the power from each machine without leaving his position at the
point o f operation.
(d ) F or general rules regarding starting and stopping devices,
emergency stops, etc., see Safety Code for Mechanical Power-Transmission Apparatus.
Rule 201. Self-feed.
It is recommended that automatic feeding devices on machines be
installed wherever the nature o f the work will permit.
Rule 202. Speeds.
(a)
Circular saws.— The table gives the maximum permissible
speed in revolutions per minute for various sizes o f circular saws.
For ordinary operation the speeds given in the second column shall
not be exceeded. Where high-speed saw blades are used, speeds not
to exceed those given in the third column may be permitted if so
recommended by the manufacturer. Blades for operation at high
speeds shall be understood to mean blades o f alloy steel having an
elastic limit not less than 150,000 pounds per square inch specially
tensioned to run smoothly at the speed employed.

SAFETY CODE FOE WOODWORKING PLANTS

(b) Band saws.
1. No band-saw wheel shall be run at a speed in excess o f that
which will allow a factor o f safety of 10 in all parts o f the wheel,
2. The wheel and also the frame o f each machine shall be marked
by the manufacturer in letters not less than one-quarter o f an inch in
height showing this maximum allowable speed in revolutions per
minute.
3. Band-saw wheels shall be so designed, manufactured, and
mounted that they will run true at the maximum allowable speed
without excessive vibration.
PART III.— WOODWORKING MACHINERY
SECTION 30. CIRCULAR CROSSCUT, RIP, RESAW , AND SWING
CUT-OFF SAWS
N o te to se ctio n 3 0 .— It is recognized that these standards for saw guards
are not perfectly applicable to all operations for which saws are used.

The standards given are those upon which woodworkers have agreed as most
generally useful.
Since there are a considerable number of cases not satisfactorily met by
these standards, the enforcing authority should exercise rather wide latitude

in allowing the use of other devices which give promise of affording adequate
protection.
It may be expected that by so doing further progress in saw guarding will
be encouraged.

Rule 300. Crosscut table saws.
Each circular crosscut saw shall be guarded by a hood which shall
cover the saw at all times at least to the depth o f the teeth. The
hood shall adjust itself automatically to the thickness of, and shall
remain in contact with, the material being cut. The hood shall also
be so designed as to protect the operator from flying splinters and
broken saw teeth.
Rule 301. Ripsaws.
(a) Each circular ripsaw shall be guarded by a hood which shall
cover the saw at all times at least to the depth o f the teeth. The
hood shall adjust itself automatically to the thickness of, and shall
remain in contact with, the material being cut. The hood shall also
be so designed as to protect the operator from flying splinters and
broken saw teeth.
(b) Each circular ripsaw (other than self-feed ripsaws with a
roller or wheel back o f the saw) shall be furnished with a device to
prevent material being thrown back on the operator. The provision
o f a spreader in connection with grooving, dadoing, or rabbeting is
not required.
Rule 302. Circular resaws.
(a) Each circular resaw shall be guarded by a hood or shield of
metal above the saw. Such hood or shield shall be so designed as
to guard against danger from flying splinters or broken saw teeth.
( b ) Each circular resaw (other than self-feed saws with a roller
or wheel at back o f the saw) shall be provided with a spreader
fastened securely behind the saw. The spreader shall be slightly
thinner than the saw kerf and slightly thicker than the saw disk.




SAFETY CODE FOR WOODWORKING PLANTS

&

Rule 303. Feed rolls.
Feed rolls shall be protected by a semicylindrical guard to prevent
the hands o f the operator from coming in contact with the in-running
rolls at any point. The guard shall be constructed of heavy material,
preferably metal, adjustable to the size o f the stock being cut and
firmly secured to the frame o f the machine.
Rule 304. Swing cut-off saws.
Each swing cut-off saw shall be provided with a metal hood, so
arranged that the part o f the saw above the table is covered to at
least the root o f the teeth. This hood shall be constructed in such a

SECTION 60.— INSPECTION AND M AINTENANCE

Rule 600. Inspection.
A ll woodworking machinery should be inspected at intervals not
exceeding 60 days.
Rule 601. Maintenance.
(a) Dull, badly set, improperly filed, and gummed saws are re­
sponsible for a large proportion o f circular and band saw accidents.

such saws to make sure that they are properly filed, set, etc.; also
that they are removed as soon as they show indication o f becoming
dull.
(b) A ll knives and cutting heads o f woodworking machines
should be kept sharp, properly adjusted, and firmly secured.
( c ) Bearings should be kept free from lost motion and well
lubricated.

signed to machines suitable for such work.




SAFETY CODE FOE WOODWORKING PLANTS

13

Rule 611. Circular rip and cut-off saws.
(a) No foreman or other person in charge should permit a cir­
cular ripsaw to be operated with hood, spreader, or kick-back device
removed, or rendered inoperative, unless the nature o f the operation
renders it impossible o f performance with such devices, or any o f
them, in position, in which case same shall be immediately replaced
upon completion o f such operation.
(b) A ll cracked saws should be removed from service.
Rule 612. Band saws and band resaws.
(a) Before starting a band saw the blade should be tested with
fingers and proper tension secured.
( b ) The back thrust should be adjusted carefully to the normal
position o f the saw blade.
( c ) T o secure satisfactory operation, means should be provided
for preventing the accumulation o f dust on the face o f band wheels.
(d ) Using a small saw for large work or forcing a wide saw to
cut on a small radius is bad practice. The saw blade should in all
cases be as large as the nature o f the work will permit.
(e) Saws should not be stopped too quickly nor by thrusting a
piece o f wood against the cutting edge o f teeth when power is off.
( / ) Twists or kinks should be prom ptly removed with a hammer.
(g) To avoid vibration, brazed joints should not be thicker than
the saw blade.
( h) Each saw should be carefully examined as it is put on or
taken off the band wheel to detect cracks or other defects. Cracked
saws or saws which indicate probability o f breakage should be
prom ptly removed to avoid injury both to saw and to operator.
Rule 613. Lathes.
Particular care should be taken to have all material fastened se­
curely to faceplates or held properly between centers.
SECTION 62. VENEER MACHINES AND EQUIPMENT

Rule 620. Steam vats.
(a) Covers should be removed only from that portion o f steaming
vats on which men are working. A portable railing should be
placed at this point to protect the operators.
(b) Workmen should be forbidden to ride or step on logs in steam
vats.
( c ) A ll cranes, log trolleys, and other hoisting equipment used in
the veneer industry should be tested and inspected frequently.
(.d) When attaching dogs to log care should be taken not to place
hand or fingers where they might be caught between log and dog.
(e)
Particular attention should be given to inspection and mainte­
nance o f veneer saws.
( / ) Care should be taken to see that all material is securely
fastened to the saw table.
( g ) Whenever veneer slicers or rotary veneer cutters have been
shut down for the purpose o f inserting log or to make adjustments
operators should make sure that machine is clear and other work­
men are not in a hazardous position before starting the machine.

14

SAFETY CODE FOR WOODWORKING PLANTS

SECTION 63. CLOTHING AND GOGGLES WORN BY OPERATORS

Rule 630. Clothing.
(a) Gloves should not be worn while operating machines.
(b) Loose flowing garments, sleeves, neckties, etc., offer a decided
accident hazard and should not be worn by operators o f machines.
Rule 631. Goggles.
Where danger from dust, flying chips, etc., exist, proper eye pro­
tection should be provided. (See National Safety Code for the
Protection o f the Heads and Eyes o f Industrial W orkers.)
PART VII.— EXPLANATORY MATTER
SECTION 70

Rule 700. Location of machinery.
By locating heavy-duty machinery on the ground floor, most o f
the vibration due to high operating speed can be eliminated.
Rule 701. Machine foundations.
Undue vibration and noise caused by high-speed machinery may
be eliminated to a large extent by cushioning the machine founda­
tion. This can be done by inserting rubber, felt, cork, or other
elastic material between the machine base and the floor beams or
girders to which the machine is fastened. It must be borne in mind,
however, that the bolts that hold the machine to the foundation
must not pass through or touch the girders or floor beams o f build­
ing. The cushioning material must be fastened to the floor beams
or girders by bolts that are independent o f the machine base.
Rule 702. Motor drive.
The initial expense o f individual motor drive is frequently higher
than that o f other power-transmission equipment such as line shaft­
ing, etc., but has a great many advantages. It offers a better control
o f the individual machine. It also eliminates overhead shafting and
belting, thereby im proving lighting and general appearance o f shop.
Then, too, it eliminates injuries due to oiling and maintenance o f
overhead transmission equipment.
Rule 703. Lighting.
Proper lighting is o f vital importance. It is a widespread belief
among men experienced in accident prevention work that 25 per
cent o f all avoidable accidents in the country are due to improper
lighting. Too much is often as bad as insufficient illumination. The
Lighting Code gives values o f intensities. It is also important that
proper attention is given to the maintenance o f all lighting equip­
ment, i. e., cleaning and adjustment o f reflectors. Dust accumulated
on the lamp bulbs quickly cuts down the intensity o f the light.
Makeshift reflectors or those whose adjustment has been impaired
have a tendency to spoil the efficiency o f any carefully worked out
lighting system.
Rule 704. Selection of suitable machines.
Under rule 610 o f this code the statement is made that machines
should not be used fo r operations o f such variety as to necessitate the




SAFETY CODE FOR WOODWORKING PLANTS

15

removal o f safeguards suitable for the usual service. It is well to
plan or route the work in such a way as to avoid too frequent adjust­
ment o f machines and altering o f position o f guards. The proper
regard for this rule will increase production by reducing the time
lost due to making adjustments, and will also reduce accidents by
insuring continued use o f safeguards suitable to the work.
Rule 706. Care of machines and tools.
Dull and improperly set tools are the direct cause o f many acci­
dents which are attributed to carelessness of operator or lack o f
proper guards.
Rule 707. Cracked saws.
The practice o f drilling the end o f a crack in a saw to prevent
further cracking should not be permitted, as the use o f such a saw is
extremely dangerous. Cracked saws should not be used.
Rule 708. Wabble saws.
In some plants it is customary to rig up a circular saw by insert­
ing wedges between the saw disk and the collar to form what is com­
monly known as a wabble saw. This saw is used for the work ordi­
narily performed by a dado saw. This practice is dangerous and
should not be permitted.
